Danger to life as a result of undesirable motor motion when the system powers up and the
drives are activated after hardware and/or software is changed or replaced
After hardware and/or software components have been modified or replaced, or after drive
parameters are changed or parameter backups are loaded, it is only permissible for the
system to run up and the drives to be activated with the protective devices closed.
Personnel shall not be present within the danger zone during this time.
• It may be necessary to carry out a partial or complete acceptance test or a simplified
functional test after making certain changes or replacements.
• Before personnel may re-enter the hazardous area, all of the drives should be tested to
ensure that they exhibit stable control behavior by briefly moving them in both the plus
and minus directions (+/-).
